What does SSPC-SP10 involve in terms of surface preparation?

• A. Brush-off cleaning
• B. Power Tool Cleaning to Bare Metal
• C. Commercial grade cleaning
• D. Surface prep of concrete

Answer: (B)

SSPC-SP10 refers to Near-White Blast Cleaning. This means the surface is prepared by abrasive blasting to remove coatings and most surface contaminants, leaving the steel in a condition close to bare metal. The goal is a surface that is largely free of paint, rust, oil, and residues, with only slight staining or light oxidation remaining. This level of cleanliness provides excellent adhesion for subsequent coatings and is achieved with blasting media and equipment, not with hand or power-tool cleaning. It’s more thorough than brush-off cleaning and is distinct from surface prep methods aimed at concrete or other substrates.
